Step-by-step explanation:

Considering speed of Noha = 4miles per hour

and speed of andrew = 2 miles/hour

The distance between Noha and andrew = 15 miles

Case 1: when they are travelling towards each other( opposite direction)

Then their relative speed becomes = 4+2 = 6miles/hour

Time taken to meet = Distance/relative speed = 15/6 = 2.5 hours

Case2: When they are travelling same direction

Then their relative speed becomes = 4-2 = 2 miles/hour

Time taken to meet = Distance/ relative speed = 15/2 = 7.5 hours

Answer:

(x - 1)^2 + (y + 2)^2 = 4^2

Step-by-step explanation:

The standard equation of a circle of radius r with center at (h, k) is

(x - h)^2 + (y - k)^2 = r^2

Replacing h with 1, y with -2 and r with 4, we get:

(x - 1)^2 + (y + 2)^2 = 4^2

Answer:

t ≤ 10

Step-by-step explanation:

To solve the inequality, simplify it.

-3t + 9 ≥ -21

Subtract 9 from both sides.

-3t ≥ -30

Divide by -3. When dividing by a negative, flip the inequality sign.

The answer is C, t ≤ 10.

Answer:

First we subtract 8,500 from the 18,040. What we get from that is 9540. Now we divide 9,540 by 3.8 and see what we get. What we get is 2510.52631579 which means it would take around 2510.52631579 days to pay 18,040. In total that rounds to 7 years. Rounding up by the way

Answer:

0.875 or 7/8

Step-by-step explanation:

you divide 1/2, 1/4, 1/8 into their decimal form and you add them all up into 0.875 and you turn it into its fraction form and get 7/8

Exponents first

Area: ½ x (sum of the lengths of the parallel sides) x perpendicular distance between parallel sides

Area = 1/2( 8 + 14) 5 = 1/2× 22 × 5 = 55 ft^2

3•2=6

Answer: B

Step-by-step explanation:

Answer:

27

Step-by-step explanation:

Givens

b1 = 13

b2 = ?

h = 6

Area = 120

Formula

Area = (b1 + b2) * h/2         Multiply by 2

2Area = (b1 + b2)*h           Divide by h

2Area/h = b1 + b2              Subtract b1 from both sides

2Area/h - b1 = b2

Solution

2*120 / 6 - 13 = b2

40 - 13 = b2

b2 = 27

It is always handy to solve an equation in the form that finds the unknown on one side. It makes the solution much easier.

Answer:

246 or 468.

Step-by-step explanation:

The only possible even digits are 2, 4, 6, and 8 (0 is neither even nor odd).

Therefore, your possible numbers are 246 and 468.

Answer:

C) -0.103 and D) 0.204

Step-by-step explanation:

A linear model with a weak correlation is gonna have an r value closest to 0, whether it be negative or positive. C and D seem to be the best choice as they're closest to 0.

Answer:

D

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift left of a units

• If a < 0 then a shift right of a units

Then

g(x + 3)² is the graph of f(x) translated 3 units left

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Then

g(x) = g(x + 3)² - 7 is the graph of f(x)

Translated 3 units left and 7 units down

c

Step-by-step explanation:

Answer:

using trigonometric ratio sin, which is

sin[tex]\alpha[/tex]=opp/hyp to mean opposite/ hypotenuse

sin 40°= x/9

multiply both sides of this by 9 to remove the 9 in the side we have x, we will have

sin 40°/9=x

sin° 40 =0.7451

so x= 0.7451/9

which is

x= 0.0827888888

to give it in 3 decimal places, the answer will be 0.083 since 7 is the fourth number and is more than five, we add 1 to the 2 making it 3

Answer:

6

Step-by-step explanation:

The rate can be calculated as follows

x + x -16

2x-16

(2x-16)×5

10x - 80= 800

10x = 300-80

10x, = 220

x = 220/10

= 22

22-16

= 6 mph

Hence the rate of the west bound tsin is 6mph

Answer:

x = 5

Step-by-step explanation:

Given that,

First side of a triangle = x+2

The second side of a triangle = 8

The third side of a triangle = x

We know that, perimeter is equal to the sum of all sides. So,

x+2+x+8 = 20

2x+10 = 20

2x = 10

x = 5

Hence, the value of x is equal to 5.

Answer:

Absolute minimum / vertex = (5/6,-133/12)

Step-by-step explanation:

Since a is positive, then the absolute maximum is ∞. The absolute minimum would be the vertex of the parabola, meaning x=-b/2a=-(-5)/2(3)=5/6, and y=3(5/6)^2-5(5/6)-9 = -133/12. Therefore, your absolute minimum / vertex is (5/6,-133/12)
